Thanks Jason for the valuable inputs.
Here is the new generic interface.

Bottom driver defines net_device_ops. The upper driver can override it.
For example, upper driver can implement ndo_open() which calls bottom driver's
ndo_open() and also do some book keeping.

Thanks Jason for the valuable feedback.
Here is the revised HFI VNIC patch series.
ChangeLog:

v1 => v2:
a) Removed hfi_vnic bus, instead make hfi_vnic driver an 'ib client',
as per feedback from Jason Gunthorpe.
b) Interface changes, data structure changes and variable name changes
